Common Issues
SDK not loading / No data appearing
Check these common causes:
- Verify your Project ID is correct
- Check browser console for JavaScript errors
- Ensure the SDK script is in the
<head> - Disable ad blockers which may block tracking scripts
- Check if the domain is added to your project settings
Experiment not showing changes
Visual editor changes not appearing:
- Clear your browser cache or use incognito mode
- Check if the experiment is Published (not Draft)
- Verify URL targeting rules match the current page
- You might be bucketed into the Control variant
- Check if the experiment has reached its end date
Goals not tracking conversions
Conversions not being recorded:
- Verify the goal is attached to your experiment
- Check URL patterns or CSS selectors are correct
- For custom events, ensure
CRO.track()is called - Conversions are only counted for users in the experiment
Session recordings not appearing
No recordings in your dashboard:
- Recordings may take a few minutes to process
- Check your plan's recording limits
- Verify recording is enabled in project settings
- Some pages may be excluded from recording
Frequently Asked Questions
How long should I run an experiment?
Run until you reach statistical significance (95%+ probability to win) with at least 100 conversions per variant. For most sites, this means 1-4 weeks. Always run for at least one full week to account for day-of-week variations.
Does EarlyCRO affect page speed?
Our SDK is under 15KB gzipped. A small script runs first and applies changes before the page paints, and the rest loads in the background.
Can I run multiple experiments on the same page?
Yes, but be careful about interactions. If experiments modify the same elements, you may get unexpected results. For cleanest data, test one thing at a time per page section.
How do I test on localhost?
Add localhost to your allowed domains in project settings. Enable debug mode to see console logs. Use the SDK's preview mode to force specific variants during development.
Are there any pages I shouldn't track?
Avoid tracking login pages, admin dashboards, and any pages with highly sensitive information. Use URL exclusion rules in your project settings to skip specific paths.
